I have Logic X. It asks for an input/output device. I set that as the Duet. I will be brining in a mono lead vocal from a mic pre. I also want to simultaneously record stereo guitar from the Axe FX through the USB connection. Can this be done? If no, how do I use the USB and record other audio tracks into Logic at the same time? Need help ASAP, in the middle of a session.:nightmare:
